[@_ttoottaa]

Thankuouuuu

[@Sg190th]

what if it's a square root inside the log?

[@ronaldjensen2948]

log( x^0.5) = 0.5 log(x) for all bases, so obviously the domain of x is x > 0.

[@lakshya5946]

@@ronaldjensen2948 nice

[@storm5492]

If the variable is in the base?

[@jannamarie7458]

Will the range be always (- infinity, + infinity) ?

[@keesha7910]

Its actually "all set of real numbers" both are the same

[@sumonal02]

Yes, for log function Range always (-inf, inf)
